Lavandula Angustifolia Extract
Explained
Lavandula Angustifolia Extract comes from the flowers and leaves of the lavender plant. It's mostly used in skincare for its scent plus a bit of skin conditioning properties.
Lab research credits it with soothing, antioxidant, and wound-supporting effects. This is largely thanks to a compound called rosmarinic acid.
Rosmarinic acid has been shown to calm inflammation signaling in skin cells (the same pathways that flare up in conditions like eczema and psoriasis). It also has real antimicrobial and antifungal activity in test-tube studies.
This ingredient is typically used in low concentrations (generally well under 1%) where it acts as a light fragrance + mild skin soother extract.
The main thing to know is that lavender contains two naturally fragrant molecules: Linalool and Linalyl Acetate. Some people's skin does perfectly fine with fragrance while others don't.
Just be sure to patch test if you have reactive skin or known plant allergies.
Linalool and Linalyl Acetate are gentle when fresh but oxidize into compounds that can cause allergic contact dermatitis when exposed to air. Patch-test studies of patients already being investigated for skin allergies found about 5-7% of patients had reactions to oxidized linalool, and 2.8% of patients reacted to oxidized lavender oil.
